ADUs & Additions in Beverly Hills
Detached ADUs, garage conversions, room additions and second storeys, designed, permitted and built. Designed, permitted and built by our own crews.
ADUs & Additions built for Beverly Hills properties
Beverly Hills projects are judged as much on how the work is run as on how it finishes. The city enforces construction hours, staging and street use tightly, and neighbours notice everything. A clean, quiet, well-sequenced jobsite is part of the deliverable here, alongside the finish quality itself. Trousdale and Benedict Canyon add hillside engineering on top of that.
Estate properties where finish quality, discretion and a clean jobsite matter as much as the design itself.
We are a design-build team, which means the people who draw your project are the people who build it. Design, engineering, permits and construction run through one project manager and our own crews, so nothing gets lost in a handoff between a salesperson and a subcontractor. We are licensed and insured, LIC #1119054.
Permits in Beverly Hills: Beverly Hills permits independently with its own plan check and design review. Standards for construction hours, staging and street use are strictly enforced, and hillside properties north of Sunset carry additional grading review.

$4,500 to $25,000+
What moves it: project type and size, whether structural engineering, Title 24 or a soils report is required, and how many jurisdictions or review bodies are involved
How We Build
Your Beverly Hills project, step by step
Feasibility
We check lot size, setbacks, utilities and access to confirm what your property will actually support.
Design & 3D
Layout, elevations and finishes, modelled in 3D so you approve the unit before submittal.
Plans & Permits
We prepare the full drawing set, handle engineering and Title 24, and manage the city submittal and corrections. In Beverly Hills that submittal goes to City of Beverly Hills Community Development Department, Building & Safety.
Foundation & Framing
Site prep, foundation, framing and dry-in by our own crews.
Systems & Finishes
Electrical, plumbing, HVAC, insulation, then kitchen, bath and interior finishes.
Final Inspection
We pass final inspection, walk the unit with you and hand over the keys.
Beverly Hills Questions
Common questions from Beverly Hills homeowners
Who issues the permits for this work in Beverly Hills?
City of Beverly Hills Community Development Department, Building & Safety. Beverly Hills permits independently with its own plan check and design review. Standards for construction hours, staging and street use are strictly enforced, and hillside properties north of Sunset carry additional grading review. We prepare the drawings, make the submittal and handle plan-check corrections ourselves, so you are not the one chasing the city.
What makes building in Beverly Hills different?
Estate properties where finish quality, discretion and a clean jobsite matter as much as the design itself. In practice that means trousdale and Benedict Canyon parcels are hillside builds requiring engineered retaining.
Which parts of Beverly Hills do you work in?
All of it, including Beverly Hills Flats, Trousdale Estates, Beverly Hills Post Office, Benedict Canyon. We are based in Los Angeles at Cahuenga Pass, so Beverly Hills is a short run for our crews rather than a job we service from out of the area.
What does adus & additions cost in Beverly Hills?
Detached ADU in this market generally runs $150,000 to $400,000+. What moves it is square footage, finish level, utility runs, and site access; garage conversions typically run well below a ground-up detached build. We give line-item pricing after seeing the site rather than quoting a number over the phone.
How long does an ADU take start to finish?
Plan a realistic year. Design and engineering typically take one to three months, city plan check and corrections add several more, and construction usually runs four to eight months depending on size and site access.
Is a garage conversion cheaper than a detached ADU?
Usually yes, and often substantially, because the foundation, walls and roof already exist. The trade-offs are that you lose the garage, and older slabs and framing sometimes need upgrading to meet current code.
Can I rent the ADU out?
California ADU law is designed to allow long-term rental, and an ADU is one of the few ways to add rentable square footage to a single-family lot. Short-term rental rules vary by city, so confirm your local ordinance before counting on that income.
Do you handle the permits?
Yes. Plans, engineering, Title 24 and the city submittal are all handled in-house, including responding to plan-check corrections. That is a service we sell on its own, so it is not something we hand off.
